ORNAMENTAL CHAlN.

SPECIFICATION forming part of Letters Patent No.. 324,582, datei August 18, 1885.

Application filed March 27, 1895.

To @ZZ whom it may conce/"n:

Beitknown thatl, JOHN OBRIG, a citizen of the United States, residing in Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Ornamental Chains, of which the following is a specification.

This invention relates to ornamental chains designed for use as bracelets, neckchains, dog-collars, and for other similar purposes.

The principal object of the invention is to produce a chain of cheap and simple construction which shallprescnt the appearance of two bars or ribbons loosely twisted together, each crossing alternately over and under the other.

Figure l of the accompanying drawings is a plan view of the chain. Fig. 2 is an inverted plan of the same, showing the preferred construction. Fig. 3 is a side elevation thereof, and Figs. 4 to 9 are enlarged detail views, Figs. 4, 5, and 6 showing one of the links in plan, elevation, and bottom plan, respective ly, Fig. 7 showing it in end elevation, and Fig. 8 showing it in transversesection, while Fig.

9 includes three views of one of the internal parts.

The remaining iigures illustrate modilications.

This chain is of that class wherein each link is formed with a pivot-pin or equivalent projection, which enters a slot inthe next adjoining link, in which slot it has sufficient freedom of play to give the desiredv amount of flexibility to the chain.

Fig. l illustrates the general appearance of the top of the chain when laid out fiat. Each link A hasthe form of a reverse curve, as best shown in Fig. 4, and on its ends areformed The links are each formed flat on their under sides, b, and curved on their upper sides, c, as best shown in Figs. 5 and 7, their side walls, d d, standing perpendicularly to the plane of their [lat under. surfaces. This shape, however,

forms no essential part of my invention,being merely the particular design in which I have embodied my mechanical improvements, and any other design that is adaptable to the mechanical features of my improved chain may 5o be substituted for the one shown.

`shown in Fig. G. Qboth the adjoining linksV have been passed (No model.)

It is a peculiarity of my invention that the end of each link connects with the middle of the next.

Each link is .formed at its middle with two holes or slots, e e, in its side Walls, d d, arranged opposite to each other. Across the bottom b there is also an opening, f, connecting the two holes or slots e e. The width of the slots or openings e f c is slightly greater than the width of the end of the link, so that the ends of the two adjoining links on opposite sides may enter them and play freely in them. The pins or projections a a, extending beyond the width of the ends of the link, enter into the hollow space inside the middle link and there engage the inner surfaces of the walls of the link, thus retaining the links together by a loose and free connection.

Thus it is seen that each link receives in its middle the ends of the two adjoining links, and its ends are connected with the middles of the two adjoining links.

Vhen the chain lies out flat, as shown at the left in Fig. 3, the ends of the links are in the bottom of the openings e e, and the pins a a are bearing against the bottoms b of the links.

At the right in Fig. 3 the chain is shown as bent to the shortest curve of which it is capable. The ends of the links are then bearing against the tops of the openings e e, which act as stops to prevent any further fleXure. Between these opposite limits the articulation of the links is very loose, and the movement of the chain is free.

I will now describe certain details of construction which are desirable-but not essential to the operativeness of my invention.

In order to provide for the insertion of the projections a a on onelink into the interior of the middle portion ofthe next, I form the bottom plate b with notches g g, extending from opposite sides of the opening f, as clearly Vhen the projections a a of through these notches into the interior of the hollow link, then these notches are closed by the insertion of plates or pieces 7L h, as shown, which are soldered or otherwise fastened in.

It will be understood that it is in any ease necessary to provide some means for the inroo sertion of the projections a c, and this may be done in various ways-as, for instance, by leaving the edge of the bottom plate b unsoldered, turning it up enough to enter the prof, jections a c, and then pressing it down and wear thereon.

soldering it; but I prefer the method shown.

In order to prevent the ends of the two links which both enter the middle of the intermediate link from interfering with each other and becoming entangled, and perhaps broken, I divide the middle of each link by a partition, B. (Shown removed in Fig. 9.) This partition stands as shown in the right-hand portion of Fig. 2, and keeps the opposite ends of the entering links apart. To it are iixed the two plates h 71 which enter and fill the notches g g, which th us serve to keep the partition in place laterally, and it is secured in the link by means ofa pin, i, which is passed through a hole in it, and also through two tubes, j j, forming part of the link, (Fig. 8,) and is riveted down on its ends.

I prefer to solder the plates h h and pins z' on all the links forming a chain or bracelet except three, and on these I simply rivet down the pin i, thus leaving it so that it may be forced out and the partitions B B in these three links removed. This may be done whenever it is desired to lengthen or shorten the chain, as it thus admits of separating these links and either leaving out the middle one of the three to shorten the chain or inserting one or more links to lengthen it. This is an important advantage. In this respect it will be seen that the function of vthc partition and pin is merely as a fastening for the plates h h, to enable them to be removed or replaced.

I will now describe the modification shown in Figs. l0 and 11.

Fig. l() is an inverted plan, and Fig. ll isa side elevation, of the chain. This 'differs from that already described, in that the ends of the links do not enter the middle of the adjoining links, but abut against theirsides. The pivotpins or projections a a are not attached directly to the ends of the links, butare joined thereto through the medium of a short slender arm, Z, and the slots e e are very narrow, being only wide enough to freely admit this arm Z, all of which is best shown in Fig. l0, where one of the` links is partly in section'. This construction is subject to the disadvantage that the abutting end of one link is liable to chafe the middle portion of the next, thus leaving a mark of The projections a a are entered through a slot, which is closed by soldering into it a plate, h.

It will-be observed that each link proved chain is,

of my ilnin fact, a lever fulcrumed at well as on the top, as shown in Fig. 12, in order that the slots e e might be extended below the line of the pivots. This involves no departure from my invention.

It is not essential that the links be thinner at their ends than at their middles, nor that they shall be of curved form, nor thatthe ends ot each link shall abut against the middles of the adjoining links endwise, as shown, since they might abut sidewise to like effect.

I claim as my inventionl. A chain wherein each link is connected atits ends to the middles of the adjoining links and the latter are connected at their ends to its middle, substantially as set forth.

2. A chain consisting of hollow links, each formed with projections on its ends, and with slots in its middle portion adapted to receive corresponding projections on the ends of the adjoining links, and each link connected atits end to the middles ot' the two adjoining links, and connected at its middle to the ends of the adjoining links, substantially as set forth.

3. A chain consisting of hollow links, each formed with projections on its ends, and with slots in its opposite sides at its middle portion to receive corresponding projections on the ends of the adjoining links, and with a partition fixed in it between said slots, for the purposes specified.

4.' A chain consisting of hollow' links, each formed with lateral projections aa on its ends, and with a slot or opening, e, on each side at its middle, of sufficient width to ad mit the end, and each link connected at its ends to the middles of the two adjoining links, and connected at its middle to the ends of the adjoining links, substantially as specied.

5. A chain consisting of hollow links,` each formed with lateral projections on its ends and with slots in its sides, and with supplementary slotsgg to admit said end projections, and plates h h., closing the slots g g, and fastening device, substantially as described, for retaining said plates in place in said slots.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

JOHN OBBIG.
